pyrogallol

Pyrogallol (Piral) is a white crystalline powder and a powerful reducing agent prepared by heating gallic acid.

Pyrogallol-phloroglucinol-6,6-bieckol, an antioxidant agent, can be isolated from Ecklonia [1].

Gallein (Mordant violet 25) is a small molecule inhibitor of Gβγ activity.

1. Swertianolin (Bellidifolin-8-O-Glucoside), mangiferin, rhodenthoside A-C, isoorientin, isovitexin, and amarogentin would serve as potential chemotaxonomic markers to differentiate Gentianaceae species. 2. Swertianolin and swertiamarin show significant hepatoprotective effect in the liver damage model induced by alpha-naphthylisot hiocyanate. 3. Swertianolin shows anti-acetylcholinesterase activity effects. 4. Swertianolin shows that it can scavenge superoxide and hydroxyl radicals with the studying method of the autoxidation of Pyrogallol and afenton.
